Lounge redesign. 3D impression and color + furniture suggestion

详细信息

I'm looking for a re design on my lounge which is currently an unloved and unwelcoming space. It's a large space we have struggled to model/layout having tried various layout options.
I'm keen to explore some alternative ideas, move items around etc, although the fireplace is somewhat fixed.
We will be removing and replacing everything in the room, nothing is 'off limits' within reason.
I'm looking for a warm and inviting place to sit and relax. Happy to consider split zones, carpet over floor, dividing wall etc.
I will need a color pallet to work from, available in the UK. Dulux etc.
I have more pics and measurements.
Must provide 3D visual and color pallet to work from.
